Patent GB-427091-A (GB)
Title: Improvements in indicating devices for displaying variable information
IPC: G09F11/34
Filed: 1933-07-15
Abstract: 427,091. Displaying. SANDOR, N., 33, Hook Road, Surbiton, Surrey. July 15, 1933, Nos. 20099/33, 33938/33, and 7437/34. [Class 3 (i)] Independent display panels 2 are raised out of position behind a window by a plurality of simultaneously rotating quick-thread screws 5, each screw operating an individual panel. Each panel 2 slides in a guide at one side, and on the other side has a screw-engaging pin 19 which is normally spring-pressed to engage a groove 20 at the top of the screw 5, but can be withdrawn at will by depressing a button 14 which acts through Bowden wire 16 and bell-crank 17. Withdrawal of the pin 19 allows the panel to drop by gravity, rubber buffers being provided to cushion the fall. The motor, which is geared to all the screws 5, is controlled by two mercury switches, one operated by the button 14 and the other by a projection on the panel 2. Release of the button 14 at the end of inspection closes one switch, the other being already closed, and causes the motor to raise the panel out of sight, till the switch operated by the panel is opened, the motor then stopping. A button 14 is provided for each panel 2, and any panel can thus be selectively brought into view. Instead of the panels being disposed above the window they may be located below, the buttons then pushing in the pin 19 and starting the motor, when pressed down, to raise the panel into view. The panel projection stops the motor, and release of the button withdraws the pin 19 and allows the panel to drop out of sight. Both arrangements may be combined in one casing to reduce front to back depth. In a modification the screws 5 are replaced by cords and pulleys, each panel having a cord wrapped round an individual drum, which is set in motion by displacing it by means of the key mechanism into contact with a friction roller rotated by an electric motor. In a development of this modification loops &c., on the cords are brought into the path of hooks on a single drum which when rotated winds the selected cord about the cylinder and raises the panel.

Abstract: 1,219,936. Type-bar making machines. LINOTYPE G.m.b.H. 29 April, 1968 [11 May, 1967], No. 20156/68. Heading B6W. A manually-operated or tape-controlled linecasting machine incorporates a device for the automatic setting of line lengths wherein the left-hand vice jaw, the assembler slide and in machines where line slugs are trimmed after casting, the saw slide, are limited in their motion by one of a plurality of stops, which is pro-selected and brought into the path of movement of one of the above line-limiting mechanisms. The arrangement is generally such that the left-hand vice jaw (1), Fig. 3 (not shown), the assembler slide (8) and the saw slide 15 are interconnected by means of gearing 18, 19, Fig. 1, so as to be simultaneously movable. The saw blade (not shown) is housed in a unit 10 which is rotated by a drive motor 14 through spindles 12, 13 and pulley 21, and which is vertically reciprocable on a saw slide 15 under the action of screw 17 driven through pulleys 24, 23, a reversible clutch 22 and pulleys 21. The slide 15 is provided with an upper-end switch 29 which, when it contacts a fixed bracket 31 on machine, halts its upward movement; a lower-end switch 30 stops downward movement of slide 15 when rod 32 is brought into contact with the switch following engagement of an angle bar 33 carried on the rod with a relatively fixed rod 27. The desired line length is thus determined by the length of the rod constituting a stop. The embodiment of Fig. 1 illustrates a carrier 25 for a plurality of rods 27 which are of pre-selected lengths and which can be given fine adjustment by means of nuts 28. A stepping switch device 26 controls rotation of the carrier 25 so that the desired rod is brought into the path of movement of the angle bar 33. Alternative embodiments include having a rotary cylindrical carrier 25 with rods 27 projecting radially outwards from holes in the periphery, Fig. 2 (not shown), or having a rotary cylindrical carrier 25 with rods 27 set in peripheral grooves parallel to the axis of the carrier, Fig. 4 (not shown). Control.-The operation of the reversible clutch 22, which can be replaced by separate clutches for upwards and downwards movement of the saw slide, and of the drive and locking means for the rotatable carrier 25, is controllable by a set of manually-operated keys, one for each rod 27, Fig. 5 (not shown), or by a system of relays controlled by punched tape.

Abstract: 212,824. Hickel, W., and Pletscher, O. Aug. 15, 1923. Fusible cut-outs.-A fuse-wire adapted to melt when overheated by the excessive temperature of a device which is supplied with current passing through the fuse is associated with a plunger which is interposed' between the severed ends of the fuse to prevent arcing. The plunger is applied substantially at right-angles to the wire; it may be spring controlled, and slidable either in guides lying between terminals or upon a rod conducting the current to the central portion of the fuse wire, A box of insulating material contains two line contacts 13 with projections L2 against which two fuse contacts 7 carried by a cover 9 are pressed when the latter is secured in position by screw 11. The foot 23 of a plunger 5 housed in a projection 3 in the box then rests upon the fuse wire 6. The plunger may be carried by the cover or the fuse and plunger may be carried by a loose insulating body which may be clamped in place by the cover or fitted direct between terminals on the consuming device. Windows 22. in the form described, permit the heat to reach the fuse through the terminals 13 and melt it at a predetermined temperature. The plunger spring 4 then ejects the fused metal into an insulating chamber 18 in the box which becomes isolated from the fuse contacts by the plates 23 filling the gap in an insulating wall 19. Projections on cover and box co-operate with the plunger to retain it in this position and to form a restricted fuse passage which the plunger is designed to fill to prevent arcing between the fuse terminals. A rod 26 for resetting the plunger when inserting a new fuse also serves as an indicator. A modification is suggested in which a tubular plunger surrounds a rod forming one circuit terminal in contact with the central portion of a fuse.
Patent GB-294150-A (GB)
Title: Improvements in methods and apparatus for the production of hydrogen
IPC: C01B3/06
Filed: 1928-07-17
Abstract: 294,150. Oxhydrique Franþaise. July 18, 1927, [Convention date]. Hydrogen is produced by reacting caustic alkali solution with silicon or ferrosilicon, under pressure in a closed generator 1, the silicon or ferrosilicon being introduced into the alkali solution in a progressive manner and in adjustable amounts. The generator is rocked about a horizontal axis 10, on a support 9. Soda or potash is introduced through the inlet orifice 3 and the required quantity of hot or cold water is added. The inlet is then closed by the plug 5 to which is attached the ferrosilicon distributor 2, consisting of a tube containing ferrosilicon, the lower end of which its provided with a freely suspended extension 4. The hydrogen is discharged through a micrometer valve 6 having a pressure gauge 7 and a safety valve 8. A rocking motion is imparted to the generator and the ferrosilicon escapes between the lower end of tube 2 and extension 4 and is thus progressively distributed and mixed with the soda or potash solution. When the pressure has ceased to increase, the apparatus is cooled by water sprinkling and the hydrogen discharged through valve 6. The apparatus is then rocked through 180‹ and the remaining contents discharged through the orifice 3. The stirring action may be increased by suspending a chain within the generator. A battery of such generators suitably connected together may be employed. Several sets of generators may be suitably connected so that their rocking motions balance one another. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the in the process of other silicon compounds besides ferrosilicon. This subject-matter does not appear in the Specification as accepted.
